Mitunduyo imayamba kutentha chifukwa cha kuwonjezera photoperiod mkati mwa masiku atali a chaka, ndiye kuti, pakakhala kuwala kwa dzuwa ndi kutentha. Ngati m'miyezi imeneyi mahatchi satenga pakati, mayendedwewo azibwerezedwa masiku 21 aliwonse, pafupifupi, mpaka masikuwo afupikiranso ndipo mawere amalowa munthawi yopumula ya nyengo yotentha (mankhwala oteteza khungu). Kutentha kwake kumakhala ndi gawo lomwe limadziwika ndikusintha kwamakhalidwe ndikusintha kwa ziwalo zake zoberekera kuti avomere amuna, komanso gawo luteal momwe samalandiranso ndikukonzekera kutenga mimba ndipo, ngati sizili choncho, amabwereza zozungulira .

Kodi mukufuna kudziwa zambiri za mare mukutentha - zizindikiro ndi magawo? Pitilizani kuwerenga nkhani iyi ya PeritoAnimal, komwe mungapeze zomwe mukufuna kuti muthe kukayika kwanu.

Kodi nthawi ya kutentha kwa mares imayamba liti?

Estrus imayamba pomwe mares amafika pokhwima pogonana, komwe kumachitika nthawi yomwe ali pakati Miyezi 12 ndi 24 mulungu. Pakadali pano, ziwalo zoberekera za mahatchi zimayamba kulumikizana ndi ziwalo zina za thupi, mahomoni amayamba kutuluka ndikuchita ndipo ovulation yoyamba imachitika, ndimasinthidwe amthupi ndi machitidwe omwe amakwiriridwa ndi wamwamuna nthawi yoyenera kutenga pakati. Ngakhale kuti mahatchi osakwana zaka ziwiri ali kale ndi kutentha, apitilizabe kukula mpaka 4wazaka a msinkhu, ndipamene adzafikire kukula kwakukulu.

Ng'ombe yamphongo ndi nyama yanyengo yayitali yokhala ndi masiku ataliatali, zomwe zikutanthauza kuti kutentha kwake kumachitika pakamawala tsiku lililonse, mwachitsanzo, mchaka ndi chilimwe. Munthawi imeneyi mahatchi amalowa m'malo otentha kangapo - yomwe imabwerezedwa masiku 21 aliwonse, pafupifupi. Mimba yake imakhala yopuma m'miyezi ina ya chaka, kulowa otchedwa mankhwala opha tizilombo, chifukwa pakakhala kuwala kocheperako, melatonin yambiri imatulutsidwa ndi pineal gland, hormone yomwe imalepheretsa hypothalamic-pituitary hormonal axis mkati ng'ombe yamphongo, yomwe ndi yomwe imalimbikitsa mazira kuti apange kusintha kwa mahomoni komwe kumayambitsa ovulation.

Zinthu zina zimayambitsa mares samabwera kutentha kapena osasinthasintha nthawi yoswana:

• Kuperewera kwa zakudya m'thupi kapena kuonda kwambiri
• Ukalamba
• Kuchuluka kwa cortisol chifukwa cha mankhwala a steroid
• Matenda a Cushing (hyperadrenocorticism), omwe ndi mahomoni opsinjika ndipo amachepetsa mphamvu ya mahosi

Nkhani ina ya PeritoZinyama yomwe ili ndi mayina ofunsidwa pamahatchi ndi maresi ingakusangalatseni.

Magawo azisangalalo za mawere

Magawo obwerezabwereza ndi zomwe zimachitika chifukwa cha mahomoni oberekera a mare amatchedwa kuzungulira kwa estrous. Mimbulu imatenga masiku pakati pa 18 ndi 24 kuti idutse magawo onse, ndiye kuti, pafupifupi masiku 21, pafupifupi, kuzungulira kumayambiranso ngati ali munyengo yake yobereka. Kuzungulira uku kumagawika magawo awiri: follicular phase and luteal phase, yomwe ili ndi magawo awiri iliyonse:

Gawo lotsatira la estrus mu mares (masiku 7 mpaka 9)

Mchigawo chino, mitsempha yamagazi yamphongo yamphongo imakula, makoma ake amakhala ndi mamvekedwe owoneka bwino, owala, ndipo khomo lachiberekero limatsitsimuka ndikutseguka, makamaka mozungulira ovulation chifukwa ma estrogen omwe amapangidwa mgawoli akuwonjezeka. Nthawi yomweyo, nyini imapepuka, imapaka mafuta ndipo imakhala yotopetsa, ndimadzi akumvera amuna. Izi zidagawika magawo awiri:

chiworku: Imatha pafupifupi masiku awiri, kukula kwamatumba komwe kumayambitsidwa ndi ma follicle olimbikitsa mahomoni (FSH) kumachitika ndipo ma estrogen amayamba kukulira.

estrus: imakhala pakati pa masiku 5 ndi 7, omwe amadziwikanso kuti gawo la estrus, kutulutsa mazira kapena kukhetsa kwa chingwe choyambirira, chomwe chimayenera kuyeza pakati pa 30 ndi 50 mm, kutengera kutalika kwa mawere. Zimachitika maola 48 kumapeto kwa sitepe iyi. Pakati pa 5-10% pamakhala kutulutsa kwamimba kawiri pomwe ma follicles awiri amakula, mpaka 25% pakakhala mares oyera, komabe, kutenga mimba kawiri mares ndiwowopsa.

Luteal gawo (masiku 14 mpaka 15)

Pambuyo pa ovulation, estrogen imachepa ndipo progesterone imakulira mu corpus luteum (kapangidwe kam'chiberekero kamene kamachokera m'maselo a follicle granulosa, motero dzina la gawolo), lomwe limatha masiku 7 chisanachitike ovulation ndipo limabweretsa kutsekeka kwa khomo lachiberekero, kukhala wotumbululuka ndi ntchofu zaulere komanso nyini kuyanika ndikukhala owoneka bwino. Izi ndichifukwa choti gawo ili limakonzekera chiberekero kuti chithandizire kutenga pathupi, koma ngati izi sizinachitike, mahatchi abwereza kuzungulira kumapeto kwake. Komanso, gawoli lagawika pawiri:

• alireza: gawo lomwe limatenga masiku awiri kapena atatu, pomwe corpus luteum imapangidwa ndipo progesterone imakula.
• Diestrus: Imatha pafupifupi masiku 12, progesterone imapangidwanso ndipo nthawi yomweyo follicle yomwe ikukula ikukula kuti itenthe ndi kutentha kwina. Pamapeto pa gawoli, corpus luteum imatulutsa ma prostaglandin, omwe ali ndi udindo wowuphwanya ndipo mahatchi amabwerera kutentha masiku awiri kapena atatu.

Zizindikiro za mare atatentha

Pali zizindikilo zingapo zomwe zimawonetsa kuti mahatchi akutentha, motero, amalola kukwatirana ndi yamphongo. Kuphatikiza pakukhumudwa kwambiri, mahatchi akutentha ali ndi izi:

• Pitirizani kugwedeza m'chiuno mwanu.
• Imakweza ndi kupindika mchira wake kuti iwonetse maliseche ake.
• Amatulutsa mamina ndi mkodzo pang'ono kuti akope wamwamuna.
• Kufiira kwa nyini.
• Imaulula clitoris poyenda mobwerezabwereza kwa milomo ya vulvar.
• Amakhala wokonda komanso wokonda, amakhalabe chete ndi makutu ake otseguka ndikudikirira kuti imfikire.

Ng'ombe iliyonse imakhala yapadera, pali zina zomwe zimawonetsa zizindikilo zowonekera kwambiri ndipo zina ndizobisika kwambiri, ndiye kuti nthawi zina mahatchi amagwiritsidwa ntchito kutsimikizira kuti mahatchiwo akutentha kapena ayi.

Ng'ombezo zikapanda kutenthedwa ndipo yamphongo imawayandikira, amakhala kutali, osawalola kuti ayandikire, apinde mchira wawo kuti abise maliseche awo, abwezere makutu awo kumbuyo ndipo amatha kuluma kapena kukankha.

Kodi kavalo amatentha?

Mahatchi amphongo samalowa kutentha, chifukwa samadutsa mkombero wa kutentha ngati akazi, koma kuchokera kukhwima amakula nthawi zonse amakhala achonde. Komabe, m'nyengo yotentha ya akazi, amakhalanso pangani chidwi kwambiri zolimbikitsidwa ndi mares.

Kuzindikira kumeneku kumachitika kudzera pama pheromones omwe mawere akamatentha amatulutsa ndi mkodzo, womwe ndi wolimba komanso wopepuka kuposa zachilendo, kudzera mu zomwe Flemen anachita. Izi zimachitika ndikubweza mkamwa kumtunda akamva fungo la mkodzo, kuti azindikire ma pheromones kudzera m'chiwalo cha vomeronasal (chiwalo chothandizira kununkhira cha nyama zina, chomwe chili m'mafupa amsanza, omwe amapezeka pakati pa mphuno ndi pakamwa, zomwe amalola kuzindikira molondola kwa mankhwalawa), limodzi ndi kugwiranagwirana, kuphethira, ndi kuyandikira nyamayo.

Munkhani ina mupeza matenda omwe amapezeka kwambiri pamahatchi.

Kodi kutentha kwa bulu ndi chiyani?

O kutentha kwa mbidzi ndi chomwe chimatchedwa kutentha komwe kumawonekera pakati Masiku 5 ndi 12 mutabereka. Kutentha koyamba kwambiri komwe kumachitika pamene mwana wamphongo ali ndi postpartum physiological endometritis ndipo chitetezo chake chikuvutika ndi izi. Chifukwa chake, chisamaliro chiyenera kusamalidwa kuti tisachoke mahatchi pafupi ndi yamwamuna muzochitika izi, makamaka mares omwe amatentha nthawi isanakwane 10-11 day postpartum, popeza endometrium yake ikubwezeretsanso ndipo ngati yamphongo yophimba, izi zimakulitsa mahatchi endometritis, yomwe ichepetsa kuchepa.

Ngati mwangozi atenga pakati, atha kukhala pachiwopsezo kwa iye ndi mwana wake wamphongo, atapita padera, kubadwa kwa mwana, kubadwa kwa mwana wobadwa kumene kapena kusungidwa kwa placenta, kukhala pafupipafupi kwa mares opitilira zaka 12 kapena kwa iwo omwe anali ndi vuto m'mimba yapitayo.

Tsopano popeza mumadziwa za mahatchi otentha komanso kutuluka kwamphongo, mutha kukhala ndi chidwi chodziwa mitundu ya mahatchi.

Ngati mukufuna kuwerenga zina zambiri zofanana ndi Mare mukutentha - Zizindikiro ndi magawo, tikukulimbikitsani kuti mulowe mu gawo lathu la Curiosities la nyama.
